The right side of the heart receives blood from the body. The left side receives blood from the lungs.
The right side receives un-oxygenated blood and pumps it to the lungs. The left side receives oxygenated blood from the lungs and pumps it out to the rest of the body.
the right atrium pumps to the right ventricle, then lungs, left atrium, left verntricle and aorta to the rest of the body
The right side of the heart pumps blood to the lungs, and the left side pumps blood to the rest of the body. The blood on the right side is deoxygenated and the blood on the left side is oxygenated.
You will always heard that humans have only two lungs . NOT RIGHT ! Humans actually have 5 lungs together . 3 in the right side and 2 in the left side . Why two in the left side ? Because of the heart occupying a lot of space there is not enough space for the other lung .
Its bigger because the right lung has more lobs then the left lung.
The right side of the heart pumps blood to the lungs
the pulmonary trunk and the right and left pulmonary arteries
The right side of the heart deals with de-oxgenated blood which is taken to the lungs by the pulmonary artery. The left side of the heart deals with the oxygenated blood which has been brought from the lungs by the pulmonary vein.
